eBay's Feedback System plays a critical in the community's
ability to trust one another. However we found in the spring of 2003 that too
many buyers were confused with how reputation information was displayed. I
redesigned the UI by unifying all member information onto a Member Profile
page, creating understandable visualizations of the data, and introducing the
feedback iconography. We also invovled the community in the design process
in order to manage the reaction to this sensitive information.

Finally our innovations on this project enabled myself and the product manager
to file a patent on the subject [Patent Pending: "Method and system for
presenting feedback information in a network-based transaction facility"].
